novel approaches to

illuminate the eye

LED technology supports ophthalmic surgery.

Currently, light fibres connected to external light sources are used to ­illuminate the posterior chamber of the eye.

Controlling the light intensity reaching the retina, the distance to the retina, as well as the exposure time of light is currently not possible ­using these fibres.

Novel approaches using specially designed light sources within the eye are very promising. In addition the interaction of illumination with tissues and ophthalmic liquids is currently being studied.
